Youtube Mturk / Crowdworking Websites

Do websites like this mess with organic engagement??
I want to buy youtube views for more viral videos. my videos now are doing about 30k view to 80k for popular ones. 250k being my most popular.
I've bought Instagram followers before and it completely messed with my engagement in a bad way.
Should I use these paid services to boost every single video right after they're uploaded?
or buy views for popular videos? or for the less popular ones?
Will these services mess with my numbers?
Open to any advice. thank you

Personally I would say if you are doing this, I would pay for likes/comments/shares on the video opposed to the views as its harder to prove the view retention of the crowdsourced views. saying that all the traffic is completely organic and not bots so it will have a positive effect on video ranking and recommendation.
